there's a 56 t-bird on ebay with a factory installed 2x4 intake, EDB9425-c, with edb-c carbs. it doesn't show a date code, but very interesting, item #230731704089. notice the s stamped in.

Thanks. It was kinda hard to read and I was'nt sure which way the number's were facing. I guess it could also be 9-1 or 1-5. Like I said it was kinda hard to read. I'll post a pic when I get home from work.

easy

The date code on your manifold shows it to be manufactured on a Sunday.All the rest of the dates mentioned were done during a normal Monday thru Friday work week.

Would you be good enough to post a picture of that date code casting on your manifold?

Mine has a 1-6 date code on it.

My manifold say 3 26 on it. I've been running it since 1971 now with injection. Looks like March was a popular month.

Mike, still lovin his 57 t'bird after 53 years!

Excellent information.I concur with all of the Ford/Mercury specs.I dont know about the "scrub" info but I would think that it is also correct.

That is a good piece of information that you have there.It took me years to find all that same info.

Not only do I have that info,I also have the majority of those parts N.I.B. 

 The 56 Mercury info you referenced was referred to as the M 260 setup. Check my avitar to see the original fender emblems for the M 260.
